Record 2,200 migrants cross into south Germany: police

German police registered a record 2,200 migrant arrivals in a key southern border region with Austria in the 24 hours to Tuesday morning, federal police said.

The arrivals spiked as passenger trains, each packed with hundreds of refugees, left Hungary and crossed through Austria to head into Germany's southern Bavaria state.

It was the highest number recorded by any of Germany's 10 federal police districts since the start of the migrant crisis that is expected to bring 800,000 newcomers to Europe's top economy this year.

The numbers were registered by the Munich police district, which stretches from the Bavarian state capital down to the Austrian border, between 0600 GMT Monday and 0600 GMT Tuesday, a police spokesman told AFP.
